CROSS-REFERENCE TO RELATED APPLICATIONS

This application is based on Japanese Patent Applications 2005-146976 filed May 19, 2005 and 2005-226783 filed Aug. 4, 2005, upon which priority is claimed.

FIELD OF THE INVENTION

This invention relates to a displaying device for game machines, which installed into the game machines including pachinko machines and slot machines.

BACKGROUND OF THE INVENTION

The game machines disclosed in the reference documents 1 and 2 (FIG. 5 to FIG. 7) have a plurality of displaying devices which are fitted as an unit as the same as the present invention. In this case, as a matter of convenience, electronic display with flat or curved surface, slot machine with mechanical rotating drum, electronic or mechanical displaying device with rotating plate, electronic or mechanical displaying device with belt shape or the like are called “displaying means”.

The movable display body of the reference document is attached the first displaying means having a rotating drum, which is formed in the shape of a matrix, to the front side thereof, provided the second displaying means which differs from the first displaying means at the plan side thereof and provided the third displaying means which differs from the first and second displaying means at the back side thereof.

Therefore, since the plurality of displaying means to appeal to the sight of the players for playing the game connect integrally around the movable display body, it makes the movable display body to rotate at the predetermined degrees (90 degrees, for example) by drive force of the drive motor so that it makes to change from the first displaying means to the second displaying means or from the second displaying means to the third displaying means as a merit.

Accordingly, the movable display body disclosed in the reference documents is arranged rotatably the displaying surface of each displaying means at the back of the base plate so as to appear selectively through the opening of the base plate of the front member (it means a game frame) of the pachinko machine, for example.

And now, FIG. 32 is a schematic explanation view pointing out the controversial points (the possibility for rotating the movable display body 1) of the prior art. The movable display body 1 of the prior art needs to attach each displaying surface 2 a, 3 a, 4 a of the first displaying means 2, second displaying means 3, third displaying means 4 through a required space 6 against a glass plate 5 a of the front member 5 of the game machines.

When there is no enough required space 6 between the fixed shaft 7 (center shaft which does not change its position) and glass plate 5 a which are provided at the center portion of the movable display body; and the movable display body 1 is arranged at the back portion of the front member 5 as shown in FIG. 32, the movable display body 1 rotates clockwise at the supporting point of the fixed shaft 7 as shown in the phantom arrow 8 so that the edge of the first displaying means 2 hits or contact the glass plate 5 a.

Therefore, in order to solve the problem, when the fixed shaft 7 of the movable display body 1 is held off the glass plate 5 a, each displaying surface 2 a, 3 a, 4 a of the movable display body 1 gets away from the glass plate 5 a remarkably.

For this problem, it appears prominently in the case that one of the displaying means 2, 3, 4 dose not have the measure (width or thickness) corresponding to the radius of the movable display body 1. It means that the movable display body 1 rotates centering on the fixed shaft 7.

So at present it has high hopes of appearance of the displaying device for game machines that the edge of the chassis does not hit or contact the glass plate although the movable display body with single or plural square-shaped displaying surfaces of the displaying means (LC screen, rectangle or belt-shaped wide display or the like, for example) rotates, and the displaying surface of the displaying means does not get away from the glass plate remarkably before and after it changes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Preferred embodiment (first embodiment) of the present invention is described in more detail below referring to the accompanying drawings. An understanding of the present invention may be best gained by reference of FIGS. 1 to 12.

(1) Environment of Practice of this Invention

FIG. 1 is a schematic explanation view of an example of the embodiment of the present invention. Reference numeral 11 is a pachinko machine having a front member, a displaying device and he like in FIG. 1. Reference numeral 12 is the front member which is called “game frame”, having an openable frame 13 which can lock, a transparent plate 14 (glass plate, for example) which is provided to the openable frame 13 and a base plate 15, which is formed in the shape of a rectangle, which is provided at the rear part of the transparent plate 14 through a predetermined space.

The displaying device for game machines X of the present invention is arranged (including the attachment device) at the backside of the base plate 15 so as to watch each displaying surface 2 a and 3 a of the displaying means 2, 3 of the movable display body 1 (as a matter of convenience, the same reference numerals in FIG. 21 are used here) from an opening 16 of the base plate 15. The detailed explanation of the pachinko machine X which is unrelated to this invention is omitted.

(2) Displaying Means, Displaying Surface, Movable Display Body

The words for the main parts of the present invention are explained here. The words of “displaying means 2, 3 and movable display body 1” mean the same as the meaning in the explanation of the paragraph of the background of the invention. Accordingly, “displaying means” of the present invention includes electronic or mechanical displaying devices relevant to the games.

In addition, the displaying surface of the present invention includes the same or different kind of the displaying surface without the appearance or function. In other word, when the displaying surface 2 a of the first displaying means 2 changes to the displaying surface 3 a of the second displaying means 3, the content of the displaying surface 3 a is the same as the content of the displaying surface 2 a (both displays are the initial screen, rotating drum screen, for example) as well as the different content of the displaying surface 2 a (for example, the displaying surface 2 a indicates the rotating drum screen, on the other hand, the displaying surface 3 a indicates another screen).

In addition, at least one of the displaying means 2 and 3 is used to play the game, and another may be used to indicate information for the game. It is not necessary to use all displaying surfaces as “game stage”. In this embodiment, all displaying surfaces are used as the game stage, and the plurality of the displaying means (independence or separation) are installed into the chassis as one unit (one example). However, the movable display body is provided the plurality of the displaying surfaces continuously by one displaying means depending on the embodiment of the present invention.

Furthermore, the movable display body switches from the first displaying means to the second displaying means or from the second displaying means to the first displaying means by the working piece which reciprocates vertically and the guide means (guide piece or guided part) which moves forward and backward in a horizontal direction (the direction which crosses the excursion of the working piece) with the working piece by manual operation or drive force of the drive motor. Thereby, the displaying surface 2 a, 3 a of the displaying means 2, 3 appear selectively as to direct to the player through the opening 16 of the base plate 15 which is positioned at the rear portion of the transparent plate 14.

(3) First Embodiment

The first embodiment of the present invention is described in more detail above referring to the description. In addition, therein no new matter for the displaying means itself and displaying surface itself in this embodiment so that the detailed explanation for function is omitted.

Here, FIG. 2(a) is a front view showing the way in which a first displaying means of a movable display body is directed to a player. FIG. 2(b) is a plan view based on FIG. 2(a). As is clear from the figures, the first displaying surface 2 a first displaying means 2 is an outer circumferential surface of a plurality of rotating drums 21 which are arranged in a matrix shape. In this embodiment, the chassis 20 of the movable display body 1 is supported vertically into a case-shaped fixed member 31 switchably. Additionally, the first displaying surface 2 a (circumferential surface of the rotating drum) does not project from a tip surface 31 a. In addition, when the displaying surfaces 2 a and 3 a projects from the tip surface 31 a of the fixed member 31 in some measure, it projects so that the first displaying surfaces come close the transparent plate 14 through the opening 16 of the base plate 15 (it is easy to see the symbol which is not shown in the figure).

The structure of the main parts is explained here. The fixed member 31 is defined as the supporting part member to the movable display body 1. As shown in FIG. 3, the fixed member 31 of this embodiment is assembled a plurality of supporting plates, bending edges thereof suitably. The front surface of the fixed member 31 which is formed in the shape of a case is opened.

According to FIGS. 2 and 3, reference numeral 32 are left and right supporting plates (facing supporting walls), and reference numeral 33 are upper and lower supporting plates (facing supporting walls).

The fitted parts 34, which are formed in the shape of a straight (not only straight shape but also curved line in some measure), are formed along the tip surface 31 a of the fixed member 31 at near side of the supporting plates 32.

The working piece 22 provided at the side of the movable display body 1, which is formed in the shape of a rod, engages with the fitted part 34. The working piece 22 can move from the one edge (upper side) to other edge (lower side) when the displaying means 2, 3 are switched.

In this embodiment, the fitted part 34 (vertical elongated guide hole) is formed vertically so that the working piece 22 reciprocates into the fitted part 34 vertically by drive force of the pair of the drive parts 40 which is arranged through an attachment plate 39 fixed on the supporting plate 33 of the fixed member 31, for example as shown in FIG. 4.

The fitted part 34 is formed as the vertical elongated guide hole, and it may be formed any vertical guide grooves which is not shown in the figures. In addition, depending on the design, it is not engaged with the fitted part 34, and the working piece 22 can reciprocate straightly through the interlocking piece (not shown in the figure) which moves horizontally along the inner wall surface of the supporting part 32 a, 33 a by force of the drive part 40, for example.

Furthermore, the pair of the left and right guided parts 35 or guide pieces 23, which is cut horizontally, is formed at the center portion approximately of the supporting plate 32. The guided parts 35 or guide pieces 23 has a function to control the rotation range of the movable display body.

In this embodiment, the guided parts 35 (horizontal elongated guide hole, horizontal window and the like) are formed at the supporting plate 32. These guided parts 35 are formed at the suitable parts of the rear of the fitted part 34 so as to cross the horizontal fitted part 34.

Additionally, the working pieces 22 move forward and backward vertically in the vertical elongated guide holes 34 of the supporting plates 32 when the displaying surfaces 2 a, 3 a are switched. In addition, the guide pieces 23 move forward and backward horizontally in concert with the working piece in the horizontal elongated guide holes of the supporting plates 32.

In this embodiment, the pin-shaped working pieces 22 and projected guide pieces 23 of the side of the movable display body 1 engage slidably with the vertical and horizontal elongated holes 34, 35 at the side of the fixed member 31.

And now, the guide pieces 23 of this embodiment have guide rollers provided at the tip portions thereof so that alternative guide plates 38 are attached along with upper edges of the guided part 35 as shown in FIG. 8. In addition, lower edges of the guided part 35 are bent at the outer side to increase thickness.

As mentioned above, the right and left guide pieces 23 move forward and backward in the guided parts 35 when the displaying means 2, 3 are changed and move forward and backward in the crossing direction to the excursion of the working piece.

Now the function of the working piece 22 and guide piece 23 are explained. The working piece 22 has a function to pull the movable display body 1 from the one edge of the fixed member 31 to another edge thereof, and the plurality of the guide pieces 23 have a function to control the rotation range of the movable display body so as to direct each displaying surface 2 a, 3 a of the movable display body 1 to the transparent plate 14.

Secondary, one example of the chassis 20 of the movable display body 1 is explained with reference to FIGS. 3(b), 4(b), 5(b) or the like. The chassis 20 of the movable display body 1 has the displaying surfaces 2 a, 3 a formed at a plurality of sidewall parts 24, 24, 24 which are positioned in the rotating direction respectively, and right and left sidewall parts 25, 25, which are faced each other, are the same shape, having six edges.

The shape of the sidewall part 25 of the chassis 20 is explained with reference to FIG. 4(b). In FIG. 4, Li is a virtual horizontal line which passes trough the shortest edge. L2 is a virtual line drawn at a slant, passing through the working piece 22 and guided piece 23. The acute angle that L1 and L2 intersect is 60 degrees. L2 intersects with the second shorter edge and the edge which faces to the second shorter edge. Accordingly, the displaying surface 2 a and another displaying surface 3 a is line symmetry based on L2. In addition, the edges at the side of the displaying surfaces 2 a, 3 a are the same length approximately. As a matter of course, the shape of the sidewall parts 25 may be formed any kind of six-edge shape. Additionally, the corner of the six-edge shape may be formed in the shape of arc (fan shape, for example).

In this embodiment, the shape of the sidewall part 25 corresponds to the shape showing the way in which the curette part of diamond is cut flatly when diamond is saw from one side, for example.

Since the working piece 22 and guided piece 23 are formed at the sidewall part 25 of the chassis 20, the sidewall part 25 faces to the inner wall surface of the supporting part 32 of the fixed member.

In addition, in this embodiment, the chassis 20 has an opening part to attach the plurality of the displaying means. A first opening part 27 is attached the first displaying means, and a second opening part 28 is attached the second displaying means having the different displaying surface from the displaying surface of the first displaying means.

Moreover, the size of one opening part 27 formed in the side and other opening part 28 which intersects the opening part 27 is desirably the same approximately.

In this embodiment, the rotating-drum-shaped first displaying means 2 with displaying surface 2 a in the curved surface shape is installed into one of the opening parts 27, and the LC second displaying means 3 with displaying surface 3 a in the vertical surface shape is installed into another opening part 28.

In addition, it is not limited element in the present invention, however, the oblong displaying means (third stage) having an arced or flat displaying surface may be installed into a sidewall 20 a positioned between the first displaying means 2 (first stage) and second displaying means 3 (second stage).

The movable display body 1 in this embodiment is switched repeatedly by drive force of the drive motor of the single or plural drive parts 40 which are arranged at the fixed member 31.

(4) Drive Part 40

The drive part 40 has a relation with the purpose of invention that it switches the displaying means automatically into the game so that it is the limited element in the present invention. Therefore, one example of the drive part 40 is explained with reference to FIG. 8. Additionally, since its composition on either side is the same, the composition of one side is explained.

Reference numeral 41 is a drive motor which is arranged at the upper part of the fixed member 31 through the horizontal attachment plate; reference numeral 42 is a drive shaft, which is formed in the shape of a screwed rod, connecting to the output shaft of the drive motor; and reference numeral 43 is a screwing body, which is formed in the shape of a sleeve, screwing the drive shaft. A bearing 44 is attached to the front surface of the screwing body 43. The working piece 22 as mentioned above is supported by the bearing 44 through the fitted part 34 of the fixed member 31. The explanation of other details-matters (guide rail 48 a fixed to the supporting plate 32 in the length direction, bearing 48 b for drive shaft, joint 48 c and the like) is omitted.

(5) Detecting Means

The first and second detecting means 45 and 46 to detect the rotation position of the movable display body 1 are arranged at the predetermined position at the side of the drive part 40. With reference to FIG. 7, reference numeral 45 is defined one (upper) first detecting means (sensor) to the index 47 which is provided at the rear wall of the screwing body 43, and reference numeral 46 is defined another (lower) second detecting means (sensor).

These detecting means 45, 46 are attached to the supporting plate 32 of the fixed member 31 through the attachment plate. The detecting means 45, 46 using a principal of a hall IC, a combination of light emitting element and light-sensitive element or the like is applied selectively.

(6) Power Supply Circuit For Drive Part

The power supply circuit 50 is explained with reference to FIG. 12. The power supply circuit 50 includes an electric power supply, a control part 51 which controls the drive motor 41 by electric current from the electric power supply, the detecting means 45, 46 which detect the rotation-position angle of the drive motor 41.

Since the control part 51 is enough to control order and operation (activation, stop) to the drive motor 41, it does not include the control part, drive motor or the like and means commercial power supply, chargeable battery, pressor circuit and the like which are not illustrated when the power supply circuit 50 is defined narrowly. In the present invention, the composition of the power supply circuit is not limited.

In FIG. 12, reference numeral 51 is a control part (micro computer) installed into the game machine 11 or displaying device X; reference numeral 49 is an AC power supply; reference numeral 52 is a file device; reference numeral 53 is a switching circuit, reference numeral is a drive motor; numeral 45 is a first detecting means; numeral 46 is a second detecting means; and reference letter a is a detected signal that the detecting means 45, 46 are detected the position (rotating position of the movable display body 1) of the index or magnet 47 of the screwing body 43.

(7) Changing Displaying Surface

The automatic switching of the displaying means 2, 3 is explained with reference to FIGS. 9 toll. FIG. 9(a) is a view showing the way in which the displaying surface 2 a of the first displaying means 2 is directed to the player. FIG. 9(b) is a view showing the way in which the working piece 22 is positioned above the fitted part 34. When the working piece 22 is positioned at an initial state, as shown in FIG. 9(b), the guide piece 23 inside the guided part 35 is positioned with engaging with the front part in the guided parts 35. FIG. 9(c) shows the way in which the displaying surface 2 a of the movable display body 1 is in a vertical state and another displaying surface 3 a is an incline state (the player cannot see it).

Now slot machine using the symbols in the first displaying means 2 is operated, and the drive motor 41 starts when the predetermined condition is clear in FIG. 9.

The horizontal drive shaft 42 rotates when the drive motor 41 starts so that the screwing body 43 starts to move from the first detecting means 45 to the second detecting means 46 as shown by the arrow. Then the working piece 22 moves linearly on the fitted part 34 with moving of the screwing body 43.

FIGS. 10(a), (b) and (c) show the explanation views showing the way in which the displaying means 2 rotates and is switched to the displaying means 3 in mid-course. In this condition, when the third displaying means 4, which is formed in the shape of a sheet, is. provided to the side surface 20 a, for example, the third oblong displaying means 4 is directed to the player, and the first displaying means 2 and second displaying means 3 can be watched at the same time. As above-mentioned description, in this embodiment, when the working piece 22 moves from the one edge 34 a of the fitted part 34 to other edge 34 b thereof, the single or plural guide pieces 23 move forward and backward into the guided part 35 in the cross direction of the excursion of the working piece 22.

When the third displaying means 4 is directed to the player, as shown in FIG. 10(b), the guide piece 23 moves backward and the working piece 22 is positioned at the center part, and the displaying surfaces 2 a, 3 a are an incline state. In this way, the working piece 22 and guide piece 23 move to concert. When the movable display body 1 rotates in the predetermined direction by moving the working piece 22 and guide piece 23 in concert, it changes from the first displaying means 2 to the second displaying means 3 (the opposite case is the same condition).

As shown in FIGS. 11(a), (b) and (c), when the second detecting means 46 detects the position of the index or magnet 47 due to move the screwing body 43 to the second detecting means 46, the control part 51 gets the signal a and turns off a switching circuit 53 timely when the player watches the displaying surface 3 a (LC screen) of the second displaying means 3 at the front. Then, the working piece 22 moves in a lower direction, and the guide piece 23 moves forward at the same time. So the game of the second displaying means 3 can be started.

In addition, when the game in the second displaying means 3 finished, the displaying means is switched from the condition shown in FIG. 11 to the condition shown in FIG. 9 since the drive shaft 42 rotates in the opposite direction. The description of the opposite action is omitted.

The other embodiments are explained here. In addition, the components are denoted by like numerals as of the first embodiment and will not be further explained in great detail. Also the new matter which is not related with the detailed matters (pulley, attachment piece, fixtures and the like) and specified elements is not explained.
